I was originally contacted by a recruiter through LinkedIn. After responding I was able to set up an appointment. Amazon was conducting a series of interviews in NYC which lasted about half a day. There were 5 interviewers (including HR) and the interview process and questions were almost identical to those defined in Cracking the Coding Interview. This was my first interview in 7 years and I have to say they did a great job of making me feel comfortable during the process. My previous experiences weren't all that great.
